How to restore LVE in XenServer?

Question

LVM

Good day to all.
There is a server that once hung up and stopped loading XenServer. Booted from LiveCD (linuxrecovery) and copied all LVE volumes to another server using dd.
Then I reinstalled XenServer.
Already on the new XenServer, I created a VDI (disk, aka LVE volume) with the same volume as before, and using dd copied the data from another server (dd if=.. of=... skip=1 seek=1 bs=32256/ dd if=.. of=... )
When starting the server, I get an error:

The server failed to handle your request, due to an internal error.  The given message may give details useful for debugging the problem.
message: xenopsd internal error: Storage_interface.Illegal_transition(_)

The check gives an error in the metadata.

I have successfully managed to restore VDIs that were previously either offline (VM) or second. But with the first - there is such a problem.
How to restore true LVE volume?

Answer 1

dd if=.. of=... skip=1 seek=1 bs=32256

But why is this? skip=1 seek=1 Why are you skipping the first 32256 bytes on the source and destination?
